We have Panasonic KX-UTG300B phones (SIP phone) which has LDAP Phonebook option.

Settings on the phone to make this work are simple:

LDAP Server Address:   

LDAP Server Port:           

LDAP Authentication ID:

LDAP Authentication Password:

LDAP Search Base:

When I go to LDAP address book on the phone I get thousands of entries listing not only users with their phone number but also all other entries like resources, empty lines(???), N/A, Distribution lists …. Etc. in short probably everything.

There is no way I can set up a filter to filter users only that have phone number set in AD.

What I need is LDAP proxy server which will be queried by our phones instead of querying AD Server directly and return filtered list (example: just entries containing information in  “telephoneNumber” attribute)

Is this possible? I’ve been trying for weeks now with no success.

Please someone, send me sample ldap.conf and slapd.conf configuration files

Thanks
